Hello,  
I want to use CoordinateTransformations package but when I add it I get the error below. I tried to add GR@0.34 but it gave similar error. I’m very new to julia, learning it as I convert Matlab code so I am stuck here. Can anyone help please? I am using Julia 1.0.1

Thank you

I think it needs a new release. You can try `add CoordinateTransformations#master`.

Thanks @kristoffer.carlsson. However, I got the same error:

Try remove the problematic package, `rm GR`.

Wanted to do that but wasn’t sure since it was installed along with one of the plotting libraries, `PyPlot` I think. So I removed `GR` and added `CoordinateTransformations` and it built its own `GR`. At any rates, it seems to have installed correctly. Thanks.
